After Lilith returns to Earth, Six and the others receive an invitation from the Demon Lord. What lies in store for them at the Demon Castle are cliché RPG events and—at long last—the battle against the final boss! ...Right?
Always bring a gun to a sword fight!With world domination nearly in their grasp, the Supreme Leaders of the Kisaragi Corporation-an underground criminal group turned evil megacorp-have decided to try their hands at interstellar conquest. A quick dice roll nominates their chief operative, Combat Agent Six, to be the one to explore an alien planet...and the first thing he does when he gets there is change the sacred incantation for a holy ritual to the most embarrassing thing he can think of. But evil deeds are business as usual for Kisaragi operatives, so if Six wants a promotion and a raise, he’ll have to work much harder than that! For starters, he’ll have to do something about the other group of villains on the planet, who are calling themselves the “Demon Lord’s Army” or whatever. After all, this world doesn’t need two evil organizations!
In the week since Lilith arrived, the Demon Lord's army has seen significant losses, prompting an invitation to Six and the others for negotiations. But could the invite into demon territory be a trap?! ...Most likely. Also, whenever someone says the words "Demon Lord", the image of some evil old guy comes to mind. So who is this beautiful woman supposed to be?!
Serving as mercenaries for the Kingdom of Grace, Snow and friends find themselves at war with the Demon King's army. Six launches an all-out assault...but how will his modern weapons fare against such unorthodox foes?
Thanks to humanity’s greatest mind, Lilith the Black, and her hypersonic anti-submarine depth charge, the pesky exploding hideout problem is fifinally resolved! Now that the Grace Branch is up and running again, it won’t be long before Lilith can return to Earth... and she intends to bring Six with her?! But fifirst, the group takes on one last job investigating the recently uncovered ruins with the help of someone they haven’t seen in a while: Patrasche Rose.
CHAOS VERSUS ORDER. After the Demon Lord Viper’s “selfdestruction,” relative peace returns to Hideout City. Now, Six and the others can turn their attention to more important matters—like how sexy their new recruit’s uniform is! But in no time at all, chaos descends yet again. The neighboring kingdom of Toris has come under the control of a new organization. When an agent of this mysterious entity starts stirring up trouble, Six and the others decide to respond the only way the Kisaragi Corporation knows how—with acts of villainy! The battle for total world domination is heating up, but will this new enemy be a match for everyone’s favorite evil organization?
It's the start of the Undead Festival, where the dead actually come back to life! Up until now, Grimm's only ever managed to die at the start of every mission and has never been useful in any way, but is this finally her time to shine?!
Problem after problem keeps cropping up at the Undead Festival—Agent Ten gets busted for his nighttime activities in Tillis’s room, Snow gets roped into scamming innocent festival attendees, and Rose starts a new life as...an old man’s dog?! Grimm, as the festival’s organizer, is the only one of them trying to take things seriously for once, but all those issues are going to look like child’s play compared to the return from the dead of...someone Six didn’t really bother to remember!
A month has passed since the cease-fire with the Demon Army, and now that the teleporter is online, Kisaragi has sent a mutant to help the invasion get back on track. But the evil organization’s plans are derailed once again when Six is dispatched on a diplomatic mission to relieve the kingdom of Grace’s terrible drought—a problem he caused by changing a rainmaking artifact’s password into something that can’t be printed on the back of a book. Is Six really the right man for the job…?
Agent Six’s squad, having failed to get their hands on the water fruit after an attack from the Sand King, are stuck wandering the desert. It’s looking bad—they’re running out of water, their capacity for rational thought is boiling away, their “survival instincts” are starting to go off the charts, and their useless necromancer is shriveling up into nothing. In the face of all that, can Six and the rest make it back from the desert alive…?!
